In the present work the total radiative losses and the total emissivity curve are calculated for an optically thin plasma using the Arcetri Spectral Code in the [FORMULA] temperature range. Checks have been made on the effects of changes in the parameters involved in the calculations, such as element abundances, ion fractions, electron density and transition probabilities on the resulting curves. Parametric fits are given for the resulting radiative losses curves and comparison is made with previous results.

Key words: plasmas – radiation mechanisms: non-thermal
